Question

how to find internal resistance in a circuit

Answer 1

Answer:

Where, e = EMF i.e. electromotive force (Volts), I = current (A), R = Load resistance, and r is the internal resistance of cell measured in ohms. In the above equation, V is the potential difference (terminal) across the cell when the current (I) is flowing through the circuit.

hope this helps you.
